Abstract

The effects of geographical area of growth and cotton variety on pulmonary activity have been evaluated through human volunteer exposure studies conducted by NIOSH and USDA at the Cotton Quality Research Station, Clemson, S.C. These studies demonstrate that carding California cottons releases dust with less human pulmonary activity than dust released from the corresponding Mississippi cottons. Dust released from Texas cottons grown in 1982 was considerably less active than the dust from Texas cottons grown in 1983. Distinct differences in the chemical compositions of the Mississippi, Texas, and California cardroom dusts were found. Aqueous extracts of the dusts were freeze-dried and then derivatized. Capillary gas chromatography revealed that the California dust extracts and the 1982 Texas dust extract were characterized by relatively higher levels of malic acid, whereas the Mississippi dust extracts and the 1983 Texas dust extracts were characterized by relatively higher mannitol levels.

摘要

美国国家职业安全与健康研究所（NIOSH）和美国农业部（USDA）在南卡罗来纳州克莱姆森的棉花质量研究站，通过人体志愿者接触研究，评估了棉花种植的地理区域和棉花品种对肺部活性的影响。这些研究表明，梳理加利福尼亚棉花所释放的粉尘，与相应的密西西比棉花所释放的粉尘相比，对人体肺部的活性更低。1982年种植的得克萨斯棉花所释放的粉尘活性，远低于1983年种植的得克萨斯棉花所释放的粉尘。研究发现，密西西比、得克萨斯和加利福尼亚的车间粉尘在化学成分上存在明显差异。将粉尘的水提取物冷冻干燥，然后进行衍生化处理。毛细管气相色谱分析表明，加利福尼亚粉尘提取物和1982年得克萨斯粉尘提取物的特征是苹果酸含量相对较高，而密西西比粉尘提取物和1983年得克萨斯粉尘提取物的特征是甘露醇含量相对较高。
